In a second embodiment, the present embodiment discloses a computer device, including: at least one processor, and a memory communicatively coupled to the processor serial port; the memory stores commands executable by the at least one processor that when executed implement the serial communication method described above.

In the fourth embodiment, the serial communication flow of the computer device including three serial ports (COM 1, COM2, COM 3) is disclosed, and each serial port is connected with a different type of sensor (sensor a, sensor B, sensor C). It is desirable to send requests to each sensor and parse its data through a computer device.
Step 1: initializing serial port parameters
Firstly, initializing computer equipment, opening three serial ports, and setting different baud rates, namely COM 1:9600 bps, COM 2:19200 bps and COM 3:38400 bps. The custom serial port communication protocol comprises a data head identification bit, a length bit, an instruction bit and a data tail identification bit so as to ensure the consistency of communication.
Step 2: automatic serial port identification
And sending a specific custom serial port command to each serial port in turn, and waiting for a reply. When a serial port replies a correct instruction, we determine that the serial port is connected with a single board to be tested, and identify the serial port as the serial port connected with the single board to be tested, and determine that the corresponding COM number is the COM number to be bound. Taking the example of receipt of a reply from COM2, it is indicated that sensor B is connected.
Step 3: intelligent control signal transmission
And the intelligent control of the micro control unit is used for sending control signals to the serial ports connected with the single boards to be tested one by one, so that the accurate control of the serial port equipment is ensured. To ensure that communication between the serial port and the sensor is established properly. At this time, a control signal is sent to COM2 to communicate with sensor B.
Step 4: establishing an intelligent serial port mapping relation
And opening a serial port for the COM number (COM 2) to be bound, and reading the signal state of the serial port. And then comparing the signal state of the serial port with the control signal, and if the signal state is matched with the control signal, establishing an intelligent mapping relation between the COM number to be bound and the sensor B. At this time, COM2 is known to be connected to the sensor B.
Step 5: data communication
And sending a custom serial port command to the identified sensor B to perform data communication. The serial port COM2 is queried, the byte number of the data in the receiving buffer area is obtained, and a byte array with the same capacity is created to store the data. Then, some bytes are read from the input buffer of the serial port COM2, and written into the byte array.
Step 6: checking the integrity of data
Ensuring that the data head identification bit, the length bit, the instruction bit and the data tail identification bit are all correct. If the data is incomplete, we store it in the new byte set, waiting for the complement at the next cycle. For the sticky packet problem caused by hardware performance, that is, byte information of a part of next instruction is still remained after a complete instruction, after the complete instruction data is intercepted, the next cycle is completed.
Step 7: data parsing and processing
And analyzing command data according to the custom serial port communication protocol to ensure correct data transmission and analysis. Such as resolving temperature data for sensor B. If an exception occurs during the data parsing process, exception handling may occur. Such as incomplete data or resolved errors, the relevant log is recorded for subsequent hardware problem troubleshooting and debugging.
The fourth embodiment demonstrates a serial port communication method, computer equipment and computer readable storage medium provided by the invention, which can be applied to various scenes requiring serial port communication, ensures the correctness and instantaneity of data transmission, and improves the universality and the application range.
